“To Russia With Love” looks at the experiences of activists living there while also examining the safety concerns of LGBT athletes from other countries vying to compete at the Sochi Olympics.

Some gay activists called for a boycott of the games; others hoped that Olympic athletes would speak out against the law.

New Zealand speed skater Blake Skjellerup — who in the film is shown training in an unsuccessful bid for a spot on his country’s 2014 Olympics team — tells The Post he was “surprised” that no one spoke up.

“I think it was a wasted opportunity and a disappointment for the Olympic movement,” says Skjellerup, 29, who came out in 2010 after competing in the Vancouver Olympics.

“In the past it has been used as a place for diversity and education to shine,” adds Skjellerup, who now lives in New York. “This was a really, really good opportunity for it to happen — and it didn’t.”

However, one outspoken voice was that of tennis icon Billie Jean King, who was part of a U.S. delegation at the closing ceremony.

She addressed the plight of LGBT Russians at a press conference in Sochi, saying, “I hope they’re safe and eventually under the law they’ll have equal rights and opportunities.”

King tells The Post via email that she wasn’t worried about saying the wrong thing.

“Almost my entire life has been about helping all of us have equal rights and opportunities … That belief is the very core of who I am and I am not overly concerned with repercussions that may arise because of my beliefs,” she says. “I am more focused on making sure we do the right thing.”

The film also documents the case of 18-year-old Vladislav Slavskiy, a Sochi gay activist who met with both Weir and King.

In a phone interview, Slavskiy says that as a teen he already was subjected to “terrible bullying” by both students and teachers.

He says the anti-propaganda law made life even worse for gay Russians.

“People who never paid attention to gays started paying attention,” according to Slavskiy, who says he was repeatedly attacked by neo-Nazis. “It was like a green light for homophobic people to beat gays.”

Weir was especially moved by meeting Slavskiy.

“He helped lift the rose-colored glasses that I wore regarding Russia,” Weir says. “This boy sat right in front of me and told these horrible stories, and you can’t leave that unaffected.”

This summer, with help from King, Slavskiy relocated to California, where is seeking asylum while attending college.

Weir — who has traveled to Russia dozens of times — still holds the country close to his heart. In recent weeks he has practiced there for an ice show planned for December and January in Moscow and St. Petersburg.

And he recounts an “amazing” incident on his last visit when a Russian man asked for a photo with Weir — and then introduced Weir to a man he said was his “husband.”

“I felt so relieved — that there is hope,” Weir says. “And I do believe that change will come from Russians themselves.”
